During the 11th week of pregnancy, it is possible to check your baby's heartbeat using a handheld Doppler device or by visiting your healthcare provider. To use a Doppler, apply gel to your abdomen and gently move the device around until you hear the heartbeat. However, it is important to note that finding the heartbeat at this stage can be challenging and may cause unnecessary anxiety if not found. Therefore, it is recommended to consult with your healthcare provider for accurate results and reassurance. They have specialized equipment and expertise to locate and monitor your baby's heartbeat effectively.
